DOUGH MIXING AND KNEADING AI PARATUSL Application filed December 19, 1912. Serial no; 737,586. v v

To al whom it may concern: Be it known that I, PHILIPP LINK, a citizen of the United States, residing at Newark, in the county ofEssex and State of New Jersey, have invented certain new and useful Improvementsin Dough Mixing and Kneading Apparatus; and I do hereby declare the following to be a full, clear, and

exactdescription of the invention,-such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specificonstructed apparatus for the purposes of properly mixing, kneading, and throwing dough, the general arrangement of the mechanism of the apparatus, both within the mixing compartment, as well as that located without the said compartment being such, so that the dough, as it is being mixed or rolled or twisted intoa plastic mass, is

caught upon a holder in a ball-shaped mass,

and is removed from the holder and thrown within the compartment in such a manner to be again caught upon the holder, the op erations of throwing and catching taking place alternately for such length of time until the dough has become perfectly aerated and kneaded, and the bread, when baked, has a perfectly white appearance.

, Other objects of this invention not at this time more particularly enumerated will be clearly understood from the followingde tailed description of the present invention.

With the various objects of the present invention in view, the invention consists, primarily, in the novel dough-mixing and kneading apparatus hereinafter. set forth; and, the invention consists, furthermore, in the novel arrangementsand combinations of the various devices and parts, as well as in the details of'the construction of the same, all of which will be more fullydescribed in Specification of Letters Patent. Patehted J [11y 28, 1914.

the following specification, andflthen finally embodied in the clauses of the claim which are appended toand which form an essen: I

The invention is clearlyillustrated in the tia l part of thisspecification."

accompanying drawings, in which v Figure 1 is a front elevation of a doughmixing and kneading apparatus showing one embodiment of the principles of the present invention; F igs, 2 and 3 are the two end views of the same; and F igi 4 is a top view of the apparatus. with'the top-cover for closing the mixing or kneading com-- partment omitted from said view. Fig. 5 is atransverse section of the apparatus, said section being takenonline 6'6 in F igQ 1, looking in the direction of the arrow a2.

.Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now to the said drawings, the

ples of the present invention, the said apformed of the longitudinally extending front side 2, the rear side 3, the ends 4, and.

the semi-cylindrically shaped bottom 5, all

arranged to provide a suitable mixing or kneading compartment or chamber 6. The upper marginal edge-portion of the said shell or casing is preferably flanged, as at reference-character '1 indicates the complete i apparatus for m xing and kneading. dough,

and showing one embodiment of the 'princi- 7, and restingupon this flange 7 is a removable coveror lid, as 8.

The reference-character l0 lndlcates a or standards, the standards being suitably pair of suit-ably shaped frame-like elements standard being provided at its upper end with a suitably constructedbearing, as 11. Rotatably mounted in the saidbearings 11 are short tubular. shaft-like members or spindles 12, each spindle 12 being rotatably 7 arranged in a tubular hub 13,- with which each end 4 of the main shell or casing of the ',apparatus is provided, the one end-portion of each spindle 12 extending part way intothe compartment or chamber 6, and the 35 shaft and has suit-ably secured thereon a driving pulley, as 27, over which 1s adaptother end-portion of each spindle extending outside of. the hub 18 in which it is arranged, and suitably mounted upon such projecting endportion of each spindle 12 is a large driving gear 14-; Within the said chamber or compartment 6 is a mixer or kneader, ntade in the form of a frame-like element comprisin a pair'of side-hubs 15, for arranging and permanently securing said frame-like element upon the inwardly projecting end-portions of the two spindles 12, so that it will rotate withthe said spin: dles. Extending in opposite directions from each side-hub 15 are a pair of carrier-arms 16 and 17, the said arms 17 being preferably made shorter than thev arms 16. Suitably connected with the free end-portions of each pair of arms 16 is a longitudinally extending rod or bar 18, and likewise suitably connected with the free end-portions of each pair of arms 17 is another longitudinally extending rod or bar 19.

notary motion of the large driving gears 14:, and hence of the spindles 12 and the said mixer or kneader within the compartment or chamber 6, is produced by a pair of .pinions 20, each in mesh with a gear 1 1,

and suitably secured upon a shaft 21, which is rotatably mounted in bearing-portlons 22 with which the said framelike element or standards 10 are provided. Rotatably mounted in other bearing-portions 23 and,-

2dof said frame-like element or standards 10 are apair of other shafts 25 and 26, one of which, as 25, is the ma n driving Y ed to pass a driving belt for operating said shaft Speed-pulleys, preferably in the form of cone-pulleys 28 and 29, are suitably mounted upon the respective shafts and 26, and over which passes a laterally slid able drive-belt 30, for gradually increasing or diminishing the speed, as may be necessary durin the dough-mixing and kneading process, and by means of which the rotary motion of the shaft 25 is conveyed to the shaft '26. The rotary motion of the shaft 26 conveyed by means of a gearwheel 32, suitably secured upon said shaft 26,to one of the pinions 20 upon the shaft 21, and by means of the pinions 20 to the large gear-wheels 14, as will be clearly understood from an inspection of the several figures of the drawings.

The means for laterally moving the drivebelt in either direction upon the conepulleys 28 and 29 is'shown more particularly in Figs. 5, 6, 7 and 8 of the drawings, and consists, essentially, of a shaft or rod 33- which-1s capable of beingrocked or oscil- ,lated to a limited degree in bearing-portions Ed in the standards or frame-like elenents 10, the said shaftor rod 33 having smtably affixed thereto by means of a set- :erably weighted, as at 38, shown in Fig. 5.

iwith relation to said shaft or red.

its one end, the said belt shifter and tensioning device 47 is weighted, as at 48, and

upon its other end it is made with a suitably formed belt-guide, as 19, through which the drive-belt 30 passes and is suitably tensioned by a roller, as 50 which is mounted in said guide, and normally bears 1n roll- I ing engagement upon the upper surface of .SiUlCl' belt 30. To remove the said roller 50 from its bearing engagement orcontact with the belt 30, the previously-mentioned operating lever 8.6, is thrown from its normal initial position shown in Fig. 3 of the drawz ings to. the dotted position indicated in the same figure, whereby the rod 33 is slightly i i a a n oscillated, and the rod 42, wlthm said rod 1331s correspondingly moved, so that the Holt-shifter receives a different angular relation to the plane of the face of the belt 30, from that shown in the several figures of ,the drawings, thus carrying the roller 50 aiway from its contact with the belt-surface,

and thereby permitting the belt 30 to run slack, as will be evident.

@As has been stated, the two spindles 12 alre hollow or tubular, and oscillatorily arranged in the said tubular spindles 12 are the journals 51 of a dough-holder, comprisa pair of downwardly extending arms or members-52', each of which is connected with a journal 51, and with which are conirected and extend a pair of angularly dispiosed and suitably curved members, as. 53,

which meet in a point, as at 5 1, which serves at proper times to hold the mixed or kfneaded dough. The normal position of the said dough-holder is that shown more particularly in Fig. 5 of the drawings, and the general arrangement of the curved members 53 is such, that during the revolutions of g the mixer or kneader, the longitudinally extending rod or bar 18 is intermittently brought into sliding engagement with the upper surfaces of the curved members 53, while the other longitudinally extending rod or bar 19, during its rotary movements does not contact with the said curved members The said dough-holder, if desired, may also be actuated by hand, by means of anarm or leve 55, mounted outside of the apparatus uponv one of the journals 51, the said arm or lever 55, being provided at its lower end with a crank or handle 56.

In Fig. 3 of the drawings, I have shown one means for holding the dough-holder in its normal initial position, against turning during the mixing and kneading operations,

and said means consists essentially of a plate-like member or bar 57 suitably secured upon one of the frame-like elements or standards 10, a stop 58 being mounted upon said plate or bar 57, and also a rod or bar 59 is pivoted to said plate or bar 57, as at 60. The portion 61 of the arm or lever 55 is held in its fixed position bet-ween the stop 58 and the end-portion 62 of the pivoted bar or rod 59, substantially as indicated in said vided with a handle-portion 63, by means of which the said rod or bar 59, and its endportion 62 may be sufliciently raised out of engagement with the arm or lever 55 to per-@ mit the oscillation of the lever and the dough-holder connected therewith, as will be clearly evident.

In order to remove the dough from within the compartment or chamber 6, after it has been properly mixed and kneaded, the main shell or casing may be suitably tilted upon its journals mounted in the frame-like elements or standards 10, the top cover or lid having been previously removed. To pro duce this tilting movement of the said main shell or casing, the latter is provided upon the outer surface of its curved bottom with a pair of correspondingly formed racks 64, and in engagement with the said racks are a pair of pinions 65, suitably mounted. upon a shaft 66. This shaft 66 is rotatably arranged in bearing-portions 67 in the standards l0, and one of its pinions 65, meshes with a gear 68 upon a short spindle 69, and which has suitably mountedthereon a wormwheel 70. This worm-wheel meshes with a worm 71 upon a shaft 72 which is rotatably arranged in a pair of bearings 73 suitably secured to one of said standards 10. Slidably mounted upon said shaft 72 isa suitably constructed frictionclutch 74 adapted to be moved in either direction upon said shaft 72, bymeans of a spring-controlled and pivotally secured operating lever 75, whereby either of the cone-surfaces 76 of the said clutch can be brought into operative engagement with a cone 77 which is suitably secured to the main driving shaft 25, as will.

be clearly understood from an inspection of Fig. 2 of the drawings.

The operation of the herein-described dough-mixing and kneading apparatus will be clearly understood from the foregoing de scription of the same, and from an inspection of the several figures of the accompanying drawings.

Of course, I am fully aware that various changes may be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as described in the foregoing specification and as defined in the clauses of the claim which is appended hereto. Hence, I
